Former Florida Gov. Jeb Bush was a lot less "low energy" in his debate technique against front-runner Donald Trump in Tuesday's GOP presidential debate, engaging in a spirited back-and-forth over Trump's seriousness as a candidate.
It all started when a college student asked a question about Trump's call to kill not only terrorists, but their families as well.
When Trump defended it, Bush jumped in to say, "This is another example of the lack of seriousness. … the idea that that is a solution to this is just is just crazy. It makes no sense to suggest this."
Trump waved his hand in a dismissive gesture.
"Look, two months ago Donald Trump said that ISIS [the Islamic State] was not our fight. ... He said that Hillary Clinton would be a great negotiator with Iran. And he gets his foreign policy experience from 'the shows.' That is not a serious kind of candidate."
Trump said the problem is that America needs "toughness," and that's not Bush.
"Jeb said when they come across the southern border they come as an act of love," Trump said.
When Bush interjected, "You said on September 30th that ISIS was not a factor," Trump said, "Are you talking or am I talking? … You interrupted me. Are you going to apologize, Jeb? No. Am I allowed to finish? Excuse me, am I allowed to finish?"
"Some of your own medicine, Donald," a smiling Bush responded. "You're not going to be able to insult your way to the presidency. … And I do have the strength. Leadership, leadership is not about attacking people and discouraging people. Leadership is about creating a serious strategy to deal with the threat of our time."
